Nursing Elites

1. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

2. A nurse is caring for a client with a chest tube post-surgery. What is the most important assessment?

• A. Ensure the chest tube is clamped periodically
• B. Check for air leaks and ensure proper chest tube function
• C. Encourage deep breathing and coughing every 2 hours
• D. Ensure the client is positioned in a high Fowler's position

Correct answer: B

Rationale: The correct answer is B: 'Check for air leaks and ensure proper chest tube function.' This is the most important assessment for a client with a chest tube post-surgery because it ensures that the chest tube is functioning properly. Checking for air leaks helps prevent complications such as pneumothorax or hemothorax. Choice A is incorrect because clamping the chest tube periodically can lead to serious complications and should not be done unless specifically ordered by a healthcare provider. Choice C is important for promoting lung expansion but is not the most critical assessment related to the chest tube. Choice D is also important for respiratory function but is not the priority when assessing a chest tube post-surgery.

3. What is the nurse's role in preoperative patient care?

• A. Provide patient education and ensure NPO status
• B. Ensure that informed consent is obtained
• C. Obtain the patient's health history
• D. Confirm the patient's surgical site

Correct answer: A

Rationale: The nurse plays a crucial role in preoperative patient care by providing education and ensuring NPO (nothing by mouth) status. This helps prepare the patient for surgery by ensuring they understand the procedure, what to expect, and also by following necessary preoperative fasting guidelines. While obtaining the patient's health history (choice C) is important for overall patient assessment, it is typically done during the preoperative assessment but does not specifically pertain to the nurse's role. Ensuring informed consent (choice B) is primarily the responsibility of the healthcare provider performing the procedure. Confirming the patient's surgical site (choice D) is usually the responsibility of the surgical team and is done immediately before the surgery to prevent errors.

4. A nurse is caring for a client who has diabetes mellitus and is experiencing hypoglycemia. Which of the following findings should the nurse expect?

• A. Bradycardia
• B. Tachycardia
• C. Hypotension
• D. Diaphoresis

Correct answer: A

Rationale: Corrected Rationale: Bradycardia is a common sign of hypoglycemia due to the body's response to low blood sugar. During hypoglycemia, the body releases epinephrine, leading to sympathetic nervous system activation. This can result in bradycardia as a compensatory mechanism to preserve glucose for vital organs such as the brain. Tachycardia, hypotension, and diaphoresis are more commonly associated with hypoglycemia when it progresses to severe stages and the body's compensatory mechanisms are overwhelmed.

5. What is the first step in managing a patient with a suspected pneumothorax?

• A. Insert a chest tube
• B. Monitor respiratory status
• C. Administer oxygen
• D. Call for assistance

Correct answer: A

Rationale: The correct answer is to insert a chest tube. In managing a patient with a suspected pneumothorax, the priority is to relieve the pressure from the pneumothorax by inserting a chest tube. Monitoring respiratory status (choice B) is important but comes after ensuring proper management of the pneumothorax. Administering oxygen (choice C) can help support oxygenation but does not address the underlying issue of pressure in the thoracic cavity. Calling for assistance (choice D) can be done concurrently with managing the pneumothorax, but the immediate intervention to address the pneumothorax itself is chest tube insertion.
